Reproduce the exact 2D image from 3D?
Set Focal length to the same value as your actual camera.  

5000 sounds way off.  Maybe you missed a decimal and it was 50.00?
Most point-and-shoot cameras are between 35 to 50.
Wide angle is lower, 18 - 30.  Zoom is 80 - 200.
Just looking at it, I would guess 50.  

Scoot your Blender camera to the same distance
from your object as it was in the real world.

After looking at the scene...

File > User Preferences:  

Add-ons tab > Import-Export tab

N to bring up right-panel  

right-click on the 3D Cursor Location
and Reset All to Default Values  

Add > Mesh > Images as Planes  

select the image you are trying to replicate  

then scale it up on the X and Y by 5  

go down to the Viewport Shading button
(bottom-center)  click Material
so you can see the image.  

Be sure to click the Photo-icon
in the top-right panel
so it won't render in your final image.  

Click on the Render tab, and under Dimensions,
Resolution:
X:    1800 px
Y:    1000 px  

this should give you the proper aspect-ratio
use the Percentage Scale for test renders
